These should be seperate circuits so lets forget the condensing unit for a moment. It should not come on because it gets the control voltage for the contactor from the indoor unit. Check your circuit board for a 3 or 5 amp fuse and make sure it hasnt blown. If it has you will get nothing past the board. If that isnt the case, you will have to start checking for supply voltage from the panel to the disconnect at your furnace, disconnect to board(transformer may also be bad) the blower motor. transformer, and circuit board are the only components indoor that effect the outdoor unit.
